I have a pair of Perkins 4-154 engines. I started them both up from the flybridge today. Had them both running for about 30 mins at 1200 rpm. Suddenly the port engine opned right up by itself. Wouldn't turn off from key or kill. button. Huge ammounts of thick white smoke from port exhaust. I ran down below and opened the engine hatch but before I could do anything, the engine shut off. I would say that it ran wide open for about 5 mins. Havn't touched it since.I'm asking for any advice on what might have caused it and what I should do next. Thank you
